Peripheral arterial disease: leg pain on walking
Peripheral arterial disease is narrowing of the leg arteries by the same process that narrows coronary arteries. The classic symptom is calf pain that comes on at a predictable walking distance and disappears within minutes of stopping. It matters for your legs — and considerably more for your heart.
Go to an emergency department immediately if a leg is
- suddenly painful, pale, cold and numb
- weak or paralysed with loss of sensation
- showing pain at rest, particularly at night, relieved by hanging the leg out of bed
- developing an ulcer or blackened area on the toes, heel or foot
- showing spreading redness with fever alongside these signs
The six Ps — pain, pallor, pulselessness, paraesthesia, paralysis, perishing cold — indicate acute limb ischaemia, which needs treatment within hours to save the limb. Rest pain and tissue loss indicate chronic limb-threatening ischaemia and need urgent vascular referral, not a routine appointment. In an emergency call 999, or go to the Royal London Hospital Emergency Department, Whitechapel Road, London E1 1FR.
Recognising claudication
- Cramping or aching in the calf, thigh or buttock on walking, at a fairly consistent distance
- Relieved within a few minutes of standing still — you do not need to sit down
- worse walking uphill, faster, or in cold weather
- cold feet, hair loss on the legs, slow-growing thickened toenails, and pale or shiny skin
- in men, erectile dysfunction can accompany aorto-iliac disease
- It is often mistaken for arthritis, sciatica or just getting older
How it is confirmed
The ankle-brachial pressure index compares blood pressure at the ankle with the arm, using a Doppler probe. It takes about fifteen minutes, is painless, and a ratio below 0.9 confirms the diagnosis. Duplex ultrasound then maps where the narrowing is. Spinal stenosis is the main mimic — that pain comes on standing as well as walking, is relieved by sitting or leaning forward rather than simply stopping, and does not follow a consistent distance.
This is a cardiovascular diagnosis
Having peripheral arterial disease means the same process is almost certainly present in the heart and neck arteries. Most people with claudication die of heart attack or stroke rather than losing a leg. That reframes the treatment: managing the cardiovascular risk is more important than treating the leg symptoms.
- Stop smoking. Nothing else comes close — it is the strongest risk factor and continuing smoking is the strongest predictor of progression and amputation.
- A statin for everyone with peripheral arterial disease, regardless of cholesterol level.
- Antiplatelet treatment, usually clopidogrel.
- Blood pressure and diabetes control.
Supervised exercise is first-line
Walk into the pain, not away from it
The evidence-based treatment for claudication is a supervised exercise programme — walking until the pain is moderate, resting until it eases, then walking again, for around 30 minutes, three times a week, for at least three months. It improves walking distance substantially, and in trials performs comparably to stenting for many people. It works by developing collateral vessels. The instinct is to avoid the pain; doing so guarantees no improvement. This is the treatment most often skipped in favour of a procedure.
Procedures
- Angioplasty and stenting for symptoms limiting quality of life despite exercise and medical treatment.
- Bypass surgery for extensive disease or where angioplasty is unsuitable.
- Urgent revascularisation for rest pain or tissue loss.
- Procedures relieve symptoms; they do not treat the underlying disease, so the medication and lifestyle measures continue regardless.
Foot care
Reduced blood supply means minor injuries heal poorly and can progress to ulcers. Check your feet daily, moisturise but not between the toes, wear well-fitting shoes, never walk barefoot, have toenails cut professionally if you cannot see or reach them, and seek help the same day for any break in the skin. This matters even more if you also have diabetes.
Why come to us. Leg pain on walking is routinely put down to age or arthritis for years. We can perform the ankle-brachial pressure index and duplex ultrasound on site in a single visit, confirm or exclude the diagnosis, and take lipids, HbA1c and kidney function in-house — because the cardiovascular workup matters more than the leg. We prescribe statin and antiplatelet treatment, arrange supervised exercise, and refer to vascular surgery through our CQC-registered partners when it is needed.
Private assessment for peripheral arterial disease in London
Peripheral arterial disease causes cramping leg pain on walking that eases with rest, and it is a marker of wider cardiovascular risk worth acting on. A private GP in East London can assess your circulation and risk factors, arrange blood tests and an ultrasound of the leg arteries, and our private cardiology team can advise on treatment. Circulation problems are assessed at our private hospital in Whitechapel, East London, within reach of Canary Wharf and the City.
Peripheral arterial disease: circulation problems in the legs
What are the symptoms of PAD?
Cramping pain in the calf or thigh on walking that eases with rest is typical; advanced disease can cause pain at rest or ulcers.
Why does PAD matter beyond the legs?
It signals a higher risk of heart attack and stroke, so managing risk factors is as important as treating the legs.
How is PAD diagnosed?
With a circulation examination, blood pressure comparison and an ultrasound of the arteries, which we can arrange.
Do I need a referral?
No — start with a private GP, who can arrange tests and onward care.
Where can I get leg circulation assessed near me in East London?
Our vein and vascular service at Whitechapel, near Canary Wharf, can assess circulation and check the ankle-brachial index.
Why does PAD matter beyond the legs?
It signals wider cardiovascular risk, so a cardiovascular health assessment and risk-factor control are important.
